Letter opener

Abstract

A letter opener is disclosed as including a body with a channel allowing an envelope to pass through, and a cutting blade extending into the channel, in which the body and the cutting blade are movable relative to each other to vary the position along the channel at which the cutting blade cuts the passing envelope. At least part of the channel is of a generally S shape.

1. A letter opener including a body member with a channel allowing an envelope to pass through, and a cutting member extending into said channel, wherein said body member and said cutting member are movable relative to each other to vary the position along said channel at which said cutting member cuts said passing envelope, and further including a carrier that engages said cutting member and that is movable relative to said body member by a button member that includes a pin member extending through a slot of said carrier. 
   
   
     2. A letter opener according to  claim 1  wherein said button member is movable relative to said slot of said carrier to move said cutting member relative to said body member. 
   
   
     3. A letter opener according to  claim 1  wherein said button member includes a pin member extending through a slot of said body member. 
   
   
     4. A letter opener according to  claim 3  wherein said button member is movable relative to said slot of said body member to move said cutting member relative to said body member. 
   
   
     5. A letter opener including a body member with a channel allowing an envelope to pass through, and a cutting member extending into said channel, wherein said body member and said cutting member are movable relative to each other to vary the position along said channel at which said cutting member cuts said passing envelope, wherein said body member includes first and second parts which are swivellably movable relative to each other, and wherein said first part includes said channel. 
   
   
     6. A letter opener according to  claim 5  wherein said first and second parts are swivellably movable relative to each other to vary the depth to which said cutting member extends into said channel. 
   
   
     7. A letter opener according to  claim 5  wherein said first and second parts are swivellably movable relative to each other to vary the angle at which said cutting member cuts a passing envelope. 
   
   
     8. A letter opener according to  claim 6  wherein said first part includes a digit engagement member operable to move said first part relative to said second part. 
   
   
     9. A letter opener according to  claim 8  wherein said digit engagement member includes a plurality of recesses operatively associated with a protrusion of said second part for releasably positioning said first and second parts at different relative positions. 
   
   
     10. A letter opener according to  claim 8  wherein said digit engagement member includes a stopper for limiting the extent of swivelling movement between said first and second parts. 
   
   
     11. A letter opener according to  claim 7  wherein said first part includes a digit engagement member operable to move said first part relative to said second part.
